[dpdk-users] rte_flow() usage of htonl() for ipv4 addr masks?

[Cliff Burdick]

It should convert to network order, although many applications it won't
matter since they use all F's. If you follow the code in flow_filtering,
indeed it's using:

#define FULL_MASK 0xffffffff /* full mask */

So it won't make any difference. The example should probably be
updated, though..
